Premier Language Center- employment agency +ticketing agency

I have recently been hired on in the UAE as an experienced and credentialed teacher for English, through Premier Language Center,16 Al Barsha Street, Dubai, UAE Tel/Fax +971-0501874916 email employment@premierlanguagecenter.com
I was asked to send my monies Western Union to a travel agent there. I am wondering if it is legitimate. My main concern is about the possibilities as an attractive single woman and human trafficking. And not just for myself, but other women possibly going over through this agency.
Any comments welcome!
